STAT_6A_Practice Score: 3.8/14 4/7 answered Question 5 Have you ever wondered what factors make it easier for some cats to be more successful in catching prey? Scientists Michelle Harris and Karen Steudel studied the morphology of 17 domesticated cats. They defined a measure of a cat's ability to catch small animals to be the cat's "take-off velocity," or TOV score (TOV score = how quickly the cat can jump off of the ground). The scientists devised an experiment to see if body mass could be used to predict a cat's TOV score. Steudel, K. & Harris, M. (2002).

Journal of Experimental Biology, 205(24), 3877-3889. https://doi.org/10.1242/jeb.205.24.3877 The following is a small bivariate dataset of the TOV scores, in centimeters (cm) per second, and body mass measurements, in grams (g), for the 17 cats involved in the experiment.
